You have to differ between the traditional popular christian view of Judas Iscariot, the Traitor, and the view of Judas as expressend in Andres Lloyd Webber’s Jesus Christ Superstar.

I think the question about Judas’ role in the Passion is more complex than just “Judas, the traitor”. Yes, Judas betrays Jesus, but without Judas’ betrayal Jesus wouldn’t die for our sins. So the problem with Judas is wether he betrayed Jesus out of free will or he did it as part of a greater plan form God’s side? Judas betrayal is a necessary part of the Passion.

The role of Judas as expresses in Jesus Christ Superstar is more of the angry follower of the lead character and when he thinks that Jesus is straying from the pure path he takes action and thereby unknowingly scracifies himself.
